xcb_big_requests_enable(3)

💅 xcb_big_requests_enable — XCB Requests, bestie

okay so real talk: this is the xcb_big_requests_enable page from the XCB Requests manual, and it's honestly short but iconic. it's giving "one job, done flawlessly." let's get into it 🎀

---

✨ NAME ✨

xcb_big_requests_enable — Enable the BIG-REQUESTS extension 🔥

---

🌸 SYNOPSIS 🌸

first things first, you gotta pull in the header:

#include <xcb/bigreq.h>

💜 Request function

xcb_big_requests_enable_cookie_t
       xcb_big_requests_enable(xcb_connection_t *conn,

💜 Reply datastructure

typedef struct xcb_big_requests_enable_reply_t {
    uint8_t  response_type;
    uint8_t  pad0;
    uint16_t sequence;
    uint32_t length;
    uint32_t maximum_request_length;
} xcb_big_requests_enable_reply_t;

💜 Reply function

xcb_big_requests_enable_reply_t
       *xcb_big_requests_enable_reply(xcb_connection_t *conn,
       xcb_big_requests_enable_cookie_t cookie,
       xcb_generic_error_t **e);

🦋 REQUEST ARGUMENTS 🦋

• conn — your XCB connection to X11. the whole vibe, the link, the situationship with the server 💫

---

⭐ REPLY FIELDS ⭐

• response_type — the type of this reply, which in this case is XCB_BIG_REQUESTS_ENABLE. this field is also chillin' in the xcb_generic_reply_t, and it's literally how you tell replies apart from each other. name-tag energy 🏷️
• sequence — the sequence number of the last request processed by the X11 server. lowkey a little receipt of progress 🧾
• length — the length of the reply, in words (and a word is 4 bytes, no cap) 📏
• maximum_request_length — the maximum length of requests supported by the server, in 4-byte units. that's the ceiling, bestie 🏔️

---

💖 DESCRIPTION 💖

so what does this actually DO? it enables the BIG-REQUESTS extension, which — as the name screams — allows for requests larger than 262140 bytes in length. big girl requests only 💅

when it's enabled, if that 16-bit length field is zero, it is immediately followed by a 32-bit length field specifying the length of the request in 4-byte units. so it's like, "the normal length slot said zero, that's your cue, look at the NEXT number instead." the way that works is so clever honestly 😭

---

🫶 RETURN VALUE 🫶

it returns an xcb_big_requests_enable_cookie_t. and here's the thing — errors have to be handled when you call the reply function xcb_big_requests_enable_reply. you don't get them handed to you upfront, you go pick them up 📬

if you'd rather handle errors in the event loop instead, use xcb_big_requests_enable_unchecked. see xcb-requests(3) for the details, iykyk ✨

🎀 ERRORS 🎀

this request does never generate any errors. not a single one. flawless behaviour, we love to see it 👑
